quickcam kernel driver confuses my kernel!

momesana

I can't get the quickcam driver to work with my logitech Quickcam express. When I load the kernel driver and then start an application like xawtv or gqcam then I can only see a black screen and after that the kernel has some major problems and asks me to reboot. As you can see below the ID of my camera (ID 046d:0870) is exactly the same hardware as described on the gentoo-wiki Quickcam-howto so it must be supported. http://gentoo-wiki.com/HOWTO_logitech_quickcam_on_2.6.x_kernel.
Any Ideas?

Thanx

here are some information:

I had (have) the same problem. Seems to be a bug in the driver, something to do with usb speed calibration when you connect the webcam to a usb hub where another usb device (like a mouse) is present.

Try and connect the webcam to a usb host which isn't used by another device.

I have the same issue so I tried plugging in the camera to each of the 8 usb ports on my case but lsusb always says

I can confirm that this is still happening in the latest qc-usb, 0.6.6 with a 2.6.24-gentoo-r4 kernel (amd64 if that matters). I have a Logitech QuickCam Express:

quickcam: QuickCam USB camera found (driver version QuickCam USB 0.6.6 $Date: 2006/11/04 08:38:14 $)
quickcam: Kernel:2.6.24-gentoo-r4 bus:2 class:FF subclass:FF vendor:046D product :0840
quickcam: Sensor PB-0100/0101 detected
quickcam: Registered device: /dev/video0
usbcore: registered new interface driver quickcam

My problem, however, is that no matter what physical port I plug my camera into, it goes onto 'bus 2' along with my mouse, while the printer always goes to 'bus 1'. (I'd show lsusb but it locks and I haven't rebooted since the last crash message)

Is there any way to write/edit a udev rule to force the printer to bus 2 and the quickcam to bus 1?

Then again, this is starting to be a lot of work for an ancient camera that I really have no use for.

I installed
media-video/qc-usb-messenger (1.7-r1)
on kernel version 2.6.24-tuxonice-r9 (x86)
But when trying to modprobe quickcam dmesg puts out following message:

I tried it on another gentoo box (x86) with no other USB things and it works just fine. This other box has a 2.6.25 kernel.
